Title: Coating gun of high viscosity material
Inventor: NAKAMURA SATOSHI
IPC: B05C5/00
Filed: 1992-02-14
Abstract: PURPOSE:To prevent the dripping of a high viscosity material from the tip of a nozzle even when the flowability of the high viscosity material is poor by providing an actuator driving a nozzle forwardly at the time of non-emission to expand the volume in a pipeline part and allowing the nozzle to retreat to the original position at the time of emission. CONSTITUTION:A nozzle 2 is inserted in the cylindrical part 10 formed to the pipeline part 3 of the leading end part of the main body of a coating gun 1 in a freely slidable manner and the nozzle 2 is mounted so as to freely advance or retreat in the center axis direction of the coating gun 1 by the drive arm 8 and cylinder 7 constituting an actuator. The nozzle 2 advances or retreats by the drive arm 8 by operating the cylinder 7 and the volume of a variable volume part 14 formed between the cylindrical part 10 and the nozzle 2 changes. The volume in the variable volume part 14 is expanded at the time of non- emission and negative pressure is applied at the position nearest to the nozzle 2 and, even when a high viscosity material inferior in flowability is used, negative pressure effectively acts on the high viscosity material and the dripping of the high viscosity material due to residual pressure is suppressed.

IPC: G01S7/48
Filed: 1992-02-14
Abstract: PURPOSE:To prevent dew condensation from occurring by providing a means for turning OFF power supply to a sensor when difference in temperature between the outside air and the inside of the sensor is larger than a predetermined value. CONSTITUTION:A sensor is installed inside a chamber, whereby control is possible such that temperature difference between inside and outside the sensor is eliminated as well as the temperature difference between inside and outside the sensor and temperature of the outside air of the sensor are measured.

IPC: F24C7/02
Filed: 1987-02-10
Abstract: PURPOSE:To improve the cooking time setting accuracy by such a procedure that, when the output of a gas sensor, after reaching an ultimate value, varies by a predetermined quantity obtained from a mean value of a plurality of data in the vicinity of the ultimate value, a time required up to that time is multiplied by a constant to obtain a heating time required henceforth.

A control part 10 turns on an analog switch 8 for a predetermined time to obtain an output of the sensor 6. When the output V of the sensor 6 reaches an ultimate value, the control part 10 reads out a plurality of data having a largest value out of the output of the sensor to obtain a mean value. When the output varies by a value obtained from the ultimate value on the standard of the mean value, a value obtained by multiplying the time t0 required up to that time by a con stant beta is set as a heating time required henceforth. By this constitution, the cooking time becomes accurate and the cooking finish is improved.
